JoyKey

This is a small macropad that simultaneously acts as game controller and an entertainment device.

The name is inspired by the Nintendo JoyCon portmanteau (Joystick Controller) except I have replaced the 2nd word with "Keypad" (Joystick Keypad). See name ideas for other things I came up with.
